Implement Media codec (JSR-135/234) to use with SIP in J2ME

[junaiddeveloper]

Hi,
I am working on JME application that include Internet telephone calls using SIP. It requires
1. SIP stack
2. Media Stack

- SIP stack (JSR-180) is available in Nokia S60 handset and SonyEricsson (JP-8) handset; and we can use it easily.

- My problem is to implement Media stack using (JSR-135/234); Media stack require
1. Capture audio voice stream.
2. Encode packets using appropriate codec.
3. Decode packets received from SIP server.
4. Play sound for user.

Step 1 and 4 is looking simple. for step 2 and 3 we need media codec to perform encoding/decoding stream.

Please provide any information about existing codec for this.


thanx in advanced.

have you seen jspeex? its java binding of Speex codec. as the website said it "It provides both the decoder and the encoder in pure Java"

It's been a while since I've worked with midp, but things like low-level access to audio hw & real time don't get along well with j2me, and I doubt there's any jsr for this. You'll have to rely on Symbian C++.
